profile.py - a simple oprofile test
This test runs oprofile and its daemon, and verifies the presence of the oprofile module, filesystem, and daemon process.

command.py patch for simpler "grep"-style searches
This patch improves the Command class for support of simple search commands.

profiler.py patch for ia64 hang - also adds calls to opreport
This patch is against R4, and contains fixes for two different hanging problems on ia64, and also adds calls to opreport to check reporting.
Verified `hts print plan` listed profiler test and `hts run --test profiler` worked well with hts-5.3-12. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2009-0047.html |
Description of problem: Tim inquired about adding oprofile testing to the hwcert test suite (this was the begining of May), Will provided some insight into the location of existing testings which could be leveraged to avoiding needing to write everything from scratch (pasted below). This should be considered for the hts 5.3 release; additionally we'll need to consider the policy impacts, do all systems require it, if so do all systems require the specialized processor support or is the time mech. enough, if just the timer mech. works is a kbase required, etc. Additional info: > > >> The tests available for oprofile are rather simple "smoke" tests to > > >> see that oprofile can be started and stopped. and whether it can > > >> collect data. You can see the tests on the single workflow for the > > >> oprofile package, /tools/oprofile/testsuite. > > >> > > >> Note that oprofile has a fall back timer interrupt mechanism. This is > > >> used if oprofile cannot identify the performance monitoring hardware > > >> or cannot use the processor's performance monitoring hardware. Some > > >> users of oprofile might be disappointed that oprofile uses the > > >> fallback timer interrupt mechanism and push for oprofile to support > > >> the processors performance monitoring hardware (e.g. IBM power > > >> processors). However, the tests pass if oprofile is able to use the > > >> either the performance monitoring hardware OR the timer interrupt > > >> mechanism. This would catch the Goldman Sach's issue, but not IBM's > > >> comment that particular processor's performance monitoring hardware > > >> is supported.
